• AD7173-8读不到ID

    你好,工程师,我最近在用AD7173-8芯片遇到一些问题。问题是这样的,我用单片机和AD7173-8通讯可以读到ID,但是断电重开后就读不到了,然后我换了一个芯片,第一次上电可以读到,但是断电重开就读不到了。AVDD1  AVDD2  IOVDD都是3.3V供电,我的单片机SPI通讯信号高电平是5V。通讯的过程中IOVDD引脚的电压是4.2V,请问是原因造成的。

    请问AD7173-8的模拟地AVSS和数字地DGND芯片内部是连通共地的吗?

  • AD7173-8 samplerate

    In my internship we are currently planning on using the AD7173-8 in a multiple channel high speed application. Using the evaluation board the speed of the device gets slowed by 128us when using multiple channels. Are there any sollutions for this problem…

  • AD7173-8 Floating Pins

    I'm intending to use the AD7173-8 in a design and have several unused pins which I'm wondering how to handle. The pins are as follows below. Please advise.

  • AD7173-8 RTD, Thermocouple type support?

    Hi, Everyone.

    I've seen AD7193(8ch) supports all type of RTD,TC.

    However I need more channel as like AD7173-8 or AD7175-8.

    Do they support all type of RTD,TC as well as AD7193?

  • AD7173-8 gain register default value

    In the AD7173-8 ADC, the default gain value is said to depend on the IC type. In the datasheet, the value is mentioned as 

    Reset: 0x5XXXX0. But I couldn't find the exact value in the datasheet anywhere.

    Thanks for any help

  • AD7173-8 and multiple channel sampling

    Hi everyone, I am trying to use AD7173-8 in an application where 3 channels are to be used and I am a little confused about that.

    In particular:

    • The AD7173-8 is connected to a microcontroller via SPI. I have configured SPI according to the datasheet…
  • AD7173-8的输出问题

    在调试AD7173-8的时候,首先发送了读IP寄存器的命令,收到的回复是30D5,也即SPI通信无误。然后将CS拉低,DIN保持高电平,但是一直等不到DOUT为低电平的状态。看datasheet上说明,默认为连续转换模式,在一次数据转换完成后在CS为低电平时DOUT变为低电平,然后可以发送命令0x44读取数据,但是我都没见到DOUT有低电平的时候,请问各位专家如何解决?

    我如何不管DOUT是否为低,直接发送0x44命令,读到的数据是个固定值。

  • AD7173-8最低采样输入多少?

    各位大牛:

    我们在用AD7173-8做电压采样时,发现,输入ADC管脚电压为5mv, ADC采样值为0

    请教各大牛:AD7173能最低识别的采样输入是多少呢?5mv都不能正常采样吗?

    谢谢

  • RE: AD7173-8 Decoupling off +/-2V5 supplies

    Hi, 

    You can refer to the AD7173-8 Evaluation Board. For analog circuitry it is recommended to decouple to AVSS but for digital it must still be DGND. 

    Thanks,
